I have a 1737 with Vista 32-bit, switched to Vista 63-bit and also use Windows 7 64-bit and used those drivers.

Also try this tweak.

Go to device manager(right click my computer, left click properties, left click hardware, left click device manager). Click on Network and then right click on your wireless adapter, left click properties, power management. Uncheck the box, allow computer to turn off this device to save power.

And i installed all drivers of vista they all work fine but only problem with wifi adopter.

Q : Did you install the Laptop Utility and the chipset drivers first?

A : Which utility ( i have install dell support center) is there any other utility tell me and about Chipset - i installed them before wifi drivers and they successfully installed.

Q : Dell does not offer Windows 7
32-bit drivers, so did you use the Vista 32-bit drivers and install them
in the compatibility mode?

Right click on the drivers
file, left click properties, left click compatibility. Change the
compatibility to Vista.(I used Vista SP2) Then right click on the
drivers, left click run as administrator.

A : Yes i used vista 32-bit drivers. They all work fine, the only problem with wifi adopter. But i installed them simply just double click on them and install not like you said (
in the compatibility mode )

And another thing this is the 3rd time i installed 7 32-bitand after installing all the drivers wifi adopter works perfect but after few days it say No adopter found.

I used Vista SP2 compatibility mode to install all the problem drivers that would not install. After you install the first three drivers I listed, you should be abke to install the broadcom drivers and get connected with the ethernet cable and then go to Intel Website and allow the tool to give you the Windows 7 drivers you need.

My Studio 1737 came with Vista 32-bit. I changed to Vista 64-bit, on a seperate partition and had a few small issues. I had to look for a couple of drivers. Found the one driver I had issues with. I then installed Windows 7 64-bit on top of the Vista 32-bit partition. I still work with Vista 64-bit as I have mismatched RAM and the graphics are fuzzy at times, especially under load.

I have the 5100 AGN, but I don't have the My WiFi Technology installed. I think I had tried this at one time, but could not get this to work. You can connect to your network, correct?

Try reading THIS ARTICLE. Certain models work and some don't and I think my computer is one that doesn't. If you provide me a link to download and install the My Wifi Technology drivers you installed, I'll try it on mine.

you r right i i told u before, after installing windows my wifi adopter works fine but after few days massege came "adopter not found". Thats the time i installed My WiFi Technology and i think My WiFi Technology is the problem. My wifi works fine with out it.

Now i have installed new windows and wifi is working fine, if after few days or weeks i again found that problem i will tell you.

but there is another problem for that i am going to make another post. it about bluray drive.

I have Windows 7 64-bit on a seperate partition, so if you'd like me to try the WiFi Technology, if you give me a link to what you installed, I'll switch partitions and try it. I think the 5100agn in my computer will not work with this, but will not be certain until I try it.

Download the zip file. Put the zip file in a folder, then unzip it to there. Go in the folder and find the Intel PROSet.msi file and double click on it. Allow it to run. Select custon. You'll see a selection with three red x's and a little arrow.

Click on the little arrow and select...

This feature will be installed on local hard drive

Restart your computer when prompted or wait about two minutes after you click finished. When you restart your computer, you should have the WiFi Technology installed.

Click start, all programs, Intel ProSet Wireless, Intel My WiFi Technology. You can then enable the technology from there.
